Your API backend is running on multiple cloud providers. You want to generate reports for the network latency of your API. Which two steps should you take? (Choose two.)

Question

Options

• AUse Zipkin collector to gather data.
• BUse Fluentd agent to gather data.
• CUse Stackdriver Trace to generate reports.
• DUse Stackdriver Debugger to generate report.
• EUse Stackdriver Profiler to generate report.

• A
  72% (33)
• B
  17% (8)
• D
  7% (3)
• E
  4% (2)

Explanation

Network latency reporting for a distributed API requires distributed tracing. Zipkin (A) is an open-source distributed tracing system that instruments services, collects timing data, and can forward traces to compatible backends. Cloud Trace (Stackdriver Trace, C) is Google Cloud's distributed tracing tool that visualizes latency and generates latency distribution reports across services. Together they collect and report on API latency. Fluentd (B) is a log aggregator, not a tracing tool. Stackdriver Debugger (D) snapshots application state for debugging, not latency. Stackdriver Profiler (E) analyzes CPU and memory usage, not network latency.
